MENDER FOR BEER-PIPES.

SPECIFICATION forming part of Letters Patent No. 669,033, dated February26, 1901.

Application led November 19, 1900- Serial No. 371010- (NO D100-[61!) Tof/,ZZ when@ it muy concern:

Be it known that I, VILLIAM J. HAYES, of Boston, in the county ofSuffolk and Commonwealth of Massachusetts, have made certain new anduseful Improvements in Menders for Beer-Pipes, of which the following isa description sufficiently i ull, clear, and exact to enable any personskilled in the art or science to which said invention appertains to makeand use the same, reference being had to the accompanying drawings,forming part of this specification, in which- Figure l is an elevationof a section of lead pipe, showing my improved mender in position; Fig.2, a vertical transverse section of the same; Fig. 3, a longitudinalsection illustrating a modiiication, and Fig. et a Sectional View of thepacking or bushing.

Like letters of reference indicate corresponding parts in the differentfigures of the drawings.

My invention relates especially to a device for temporarily unending orstopping a leak in the lead pipe which connects beer or barrelscontaining other malt liquors with the tap or With an airpressuresupply. Frequently a hole is accidentally blown in such pipes andimmediate repairs become necessary before artisans can be summoned toeffect a permanent sealing. In accomplishing this I form an opencylinder A, of sheet-brass or other flexible metal, somewhat less indiameter than the pipe. This is provided at its edges with ears or lugsb, both of which are tapped and one screw-threaded to receive a take-upscrew f. Inside this cylinder is disposed a rubber bushing cylindricaland split at 7L, Fig. 2.

In the use of the parts as thus far described when a break .9c occurs ina pipe the bushing O, if felt, rubber, or other pliable material, isdisposed around the pipe covering the aperture ai. This is thenencircled by the exible metal cylinder Aand its lugs b connected by thescrewf, whereby such cylinder may be made to compress the packing orbushing C so across the leak as to prevent flow therethrough from thepipe in a manner which will be readily understood by those conversantwith such matters.

In the form shown in Figs. 3 and 4 the eyes of the cylinder A arecrimped or lianged inward at g. The packing-ring d has formed centrallyin its inner face an annular groove y. The operation is the same as thatdescribed above. The advantages of this form are, however, that thecrimped edges prevent expansion of the packing outwardly and render itmore eii'ective in stopping the leakopening. Moreover, the groove y willadmit the ragged edges of the break 0c, (see Fig. 3,) prevent slippingon pipe B, and also add to the efficiency of the device.

Having thus explained my invention, what I claim is The split cylinderhaving lugs and inwardly-turned flanges in combination with the groovedsplit bushing and devices for connecting said lugs whereby the cylindermay be compressed against said. bushing, substantially as and for thepurpose specified.
